Diesel Fuels
Use only commercially available
vehicular diesel fuels No. 2 or No. 1
(ASTM D 975 No. 2-D or No. 1-D).
Marine diesel fuel, heating oil or the
like must not be used.
At very low temperatures the fluidity
of No. 2 diesel fuel may become
insufficient due to paraffin separation.
For this reason the vehicle comes
equipped with a fuel preheater. The
fuel preheater only works with the
vehicles interior heater operating. It
permits a trouble free engine operation
to a temperature of approximately +
14°F (-10°C) when using No. 2 diesel
fuel.
To avoid malfunctions, No. 2 diesel
fuel of a lowered cloud point is
marketed during the cold season.
At temperatures below + 14°F (-10°C)
use winterized or No. 1 diesel fuel
only. If not available, a certain quantity
of kerosene or fuel flow improver
(refer to MB Factory
Approved Service Products pamphlet)
may be added. Mixing only to be done
within the cars' fuel tank. Keroseneor
fuel flow improver has to be filled in
before the diesel fuel.
Engine power may drop according to
the proportion of kerosene. For this
reason, keep percentage of kerosene
added to the minimum necessitated by
the ambient temperature.
The following table can be used as a
reference, if adding of kerosene
becomes necessary. The mixing ratios
shown refer to the total mixture.
Ambient temperature
+ 14°F to -4°F (-10°C to -20°C)
No. 2 Diesel Fuel: 70%
Kerosene: 30%
Ambient temperature below
4 °F (-20°C)
No. 2 Diesel Fuel: 50%
Kerosene: 50%
Even in extreme climatic conditions,
the maximum mixture ratio should not
exceed 50%.
Adding of kerosene to No. 1 diesel fuel
is not recommended even at low
temperatures.
Do not blend other specific fuel
additives with fuel. They only result in
unnecessary cost, and may be harmful
to the engine operation.
Damage or malfunctions resulting from
poor fuel quality or from blending
specific fuel additives are not covered
by the Mercedes-Benz Limited
Warranty.
Warning!
Under no circumstances should
gasoline be mixed with diesel fuel.
Always follow basic safety rules
when working with any combustible
material. Do not fill the fuel tank or
mix diesel fuel and kerosene when
smoking, near an open flame or
while the vehicle's engine is running.
An explosion or fire can result.
